File be/src/runtime/runtime-filter.h:

Line 201:   bool IsFull() const { return HasBloomFilter() && bloom_filter_ == 
NULL; }

i still don't like 'full' because the metaphor only makes sense for a 
particular implementation of a filter, namely a representation as a bitmap. if 
we decided to add a second representation, such as an explicit list of 
partition keys (which may well make sense for sparse key spaces), that wouldn't 
work anymore. in fact, 'a full filter' to me evokes an image of something 
that's clogged, ie, won't let anything through. :)

maybe there's a better word/concept that expresses 'don't apply this' or 'do 
apply this'. ('applicable'?)
